Hi, I thought that I read that LS2 would support multiple storage options. Specifically, there was some discussion of including an EAV option where all responses would be included in a single table with one response per row. Was that ever implemented?

Yes, I did see that development update. Too bad. I was thinking in the context of Pooja's database API which is ongoing. It looks like it is going to support this "section flat" idea but perhaps that's the only option.

Hi, EAV model hasn't been implemented yet, but can be added as a plugin, as the porting has been done. Also now "section flat" is not the only option, we also have flat engine implemented (which is supposed to handle the LS1 response structure).
